Abstract
The utility model relates to a device for preventing oil leakage on a parallel sewing machine, in particular to a parallel sewing machine lower shaft front end oil-leakage prevention device, which comprises a shell soleplate, wherein a lower shaft is arranged below the shell soleplate, a front sleeve is sleeved on the front surface of the lower shaft, the front sleeve is provided with an oil supply pipe and an oil return groove, an oil leak gap is formed on the junction of the lower shaft and the front sleeve, and the parallel sewing machine lower shaft front end oil-leakage prevention device is characterized in that the front surface of the front sleeve on the lower shaft is provided with an oil seal, the oil return groove is communicated with the oil leak gap, and a backflow hole is formed in the junction of the oil return groove and the oil leak gap. Since the oil return groove on the front sleeve is communicated with the oil leak gap, and the front end of the lower shaft is additionally provided with the oil seal, the engine oil leaked from the oil leak gap can be completely blocked by the oil seal and backflows to an oil tray through the backflow hole between the front sleeve and the oil return groove, so that the phenomenon of the oil leakage on the front end of the lower shaft of the parallel sewing machine can be effectively solved; and the device is simple in structure, easy to realize and obvious in effect.
Description
Technical field
The utility model is the device that prevents oil impregnate on a kind of flat seam machine, particularly a kind of flat seam machine lower shaft front end oil-impermeable device.
Background technology
Flat seam machine is the most basic machine in sewing device, the stitching neat appearance that it sews, and stitching is even, and it is smooth that firmly sewing velocity is fast, and is easy and simple to handle, but flat seam machine lower shaft front end place, it is untimely oil return often to occur, causes machine oil to run off and the pollution cloth.Specifically as shown in Figure 1, be provided with lower shaft 2 below the chassis backplane 1, the front of lower shaft 2 is arranged with protheca 3, and protheca 3 is provided with fuel feed pump 4 and oil-recovery tank 5, and machine oil enters in the lower shaft 2 through fuel feed pump 4 and protheca 3, is back to food tray from oil-recovery tank 5 again.Lower shaft 2 forms oil impregnate seam 6 with the connecting portion of protheca 3, and in the process that machine runs up, oil impregnate stitches 6 normal organic oils and oozes out, and cuts off 7 owing to have between oil-recovery tank 5 and the oil impregnate seam 6, causes machine oil to run off so can't reflux after machine oil oozes out and the pollution cloth.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of existing flat seam machine lower shaft front end oil impregnate, to invent a kind of flat seam machine lower shaft front end oil-impermeable device.
The purpose of this utility model realizes as follows: described flat seam machine lower shaft front end oil-impermeable device, comprise a chassis backplane, be provided with lower shaft below the chassis backplane, the front of lower shaft is arranged with protheca, and protheca is provided with fuel feed pump and oil-recovery tank, and the connecting portion of lower shaft and protheca forms the oil impregnate seam, it is characterized in that: on lower shaft in the front of protheca, be provided with oil sealing, oil-recovery tank is connected with the oil impregnate seam, and its junction forms a return port.
Good effect of the present utility model is as follows: because the oil-recovery tank on the protheca is communicated with the oil impregnate seam, and the front end of lower shaft has been set up oil sealing, so all blocked by oil sealing and be back to food tray by the return port between protheca and oil-recovery tank from the crevicular exudate machine oil of oil impregnate, thereby effectively solved the phenomenon of flat seam machine lower shaft front end oil impregnate; The utility model is simple in structure, realizes easily, and successful.
Description of drawings
Fig. 1 is the prior art structure chart;
Fig. 2 is the utility model structure chart.
Among the figure: 1, chassis backplane; 2, lower shaft;
3, protheca; 4, fuel feed pump;
5, oil-recovery tank; 6, oil impregnate seam;
7, cut off; 8, oil sealing;
9, return port.
The specific embodiment
As shown in Figure 2, described flat seam machine lower shaft front end oil-impermeable device, comprise a chassis backplane 1, be provided with lower shaft 2 below the chassis backplane 1, the front of lower shaft 2 is arranged with protheca 3, protheca 3 is provided with fuel feed pump 4 and oil-recovery tank 5, machine oil enters in the lower shaft 2 through fuel feed pump 4 and protheca 3, is back to food tray from oil-recovery tank 5 again, and lower shaft 2 forms oil impregnate seam 6 with the connecting portion of protheca 3, it is characterized in that: on lower shaft 2 in the front of protheca 3, be provided with oil sealing 8, oil-recovery tank 5 is connected with oil impregnate seam 6, and its junction forms a return port 9, flow into oil-recovery tank 5 from oil impregnate seam 6 machine oil that ooze out through return port 9, thus the generation of having avoided machine oil to run off and pollute the situations such as cloth.
Because the oil-recovery tank on the protheca is communicated with the oil impregnate seam, and the front end of lower shaft has been set up oil sealing, so all blocked by oil sealing and be back to food tray by the return port between protheca and oil-recovery tank from the crevicular exudate machine oil of oil impregnate, thereby effectively solved the phenomenon of flat seam machine lower shaft front end oil impregnate; The utility model is simple in structure, realizes easily, and successful.
